R507 Refrigerant Applications
Refrigeration professionals use R507 in compatible systems specifically designed for this refrigerant and in applications where current equipment specifications and regulations permit its use.
Typical service applications may include:
- Existing commercial refrigeration systems designed for R507
- Existing low-temperature refrigeration equipment
- Existing freezer systems
- Certain industrial process refrigeration applications
- Refrigerated transport applications
- Other compatible equipment originally designed for R507/R507A
Before selecting or charging R507, always verify the equipment manufacturer’s specifications, system design, and applicable EPA requirements.

EPA currently lists R-507/R-507A as acceptable for refrigerated transport and identifies it in industrial process refrigeration listings, while restrictions apply to a number of retail-food and new-equipment uses.
R507 Refrigerant Properties
| Specification | R507 |
|---|---|
| Refrigerant | R507 / R507A |
| Refrigerant Type | HFC Blend |
| Components | R125 / R143a |
| Composition | 50% / 50% |
| ASHRAE Safety Classification | A1 |
| Ozone Depletion Potential | 0 |
| Global Warming Potential | 3,990 |
| Cylinder Size | 25 lb |
| Condition | New / Factory Sealed |
| Primary Application | Existing Commercial / Low-Temperature Refrigeration |
EPA currently lists R-507/R-507A with GWP 3,990, ODP 0 and A1 safety classification.
R507 for Existing Commercial Refrigeration Systems
For example, refrigeration professionals may use R507 to service compatible existing equipment originally designed for R507 or R507A.
Its historical applications include low-temperature and commercial refrigeration equipment where consistent refrigeration performance is required.
However, technicians should always confirm the original refrigerant designation and equipment specifications before servicing a system.
R507 and Low-Temperature Refrigeration
R507 has historically been associated with medium- and low-temperature refrigeration applications.
Existing compatible systems may include freezer equipment, refrigeration racks, industrial refrigeration equipment, and other systems originally engineered for R507.
However, current EPA requirements restrict R507 in several categories of new equipment. Therefore, this product should not be marketed as universally suitable for new commercial refrigeration installations.
Important U.S. R507 Regulatory Information
R507 has a relatively high global warming potential of approximately 3,990. As the United States transitions toward lower-GWP refrigerants, EPA restrictions now limit R507/R507A in several refrigeration end uses.
For example, EPA lists R507/R507A as:
- Unacceptable in retrofit remote condensing units since July 20, 2016
- Unacceptable in new supermarket systems since January 1, 2017
- Unacceptable in several categories of new stand-alone commercial refrigeration equipment
- Unacceptable in new cold-storage warehouse equipment since January 1, 2023
R507 Retrofit and Replacement Considerations
R507 should not be marketed as a universal retrofit refrigerant.
Before changing the refrigerant in any refrigeration system, a qualified refrigeration professional should evaluate:
- Original equipment refrigerant
- Compressor compatibility
- Lubricant requirements
- Expansion devices
- System controls
- Operating pressures
- Refrigerant charge
- System capacity
- Manufacturer recommendations
- Current EPA SNAP requirements
Therefore, never assume that R507 can simply replace R404A, R22, or another refrigerant without verifying the specific application.

U.S. Refrigerant Purchase Requirements
R507 is an HFC refrigerant, and EPA sales restrictions apply to large cylinders intended for stationary refrigeration and air-conditioning service.
EPA states that these refrigerants generally may be sold to appropriately certified Section 608 technicians or qualifying organizations employing certified technicians. Sellers also have purchaser-verification and recordkeeping responsibilities.
Important Use Information
Qualified refrigeration and HVAC/R professionals should handle, charge, recover, and use R507 in accordance with applicable regulations, equipment manufacturer requirements, and established service procedures.
Always confirm that R507 is approved and legally permitted for the specific equipment and end use before servicing the system.
For current U.S. refrigerant application requirements, refer to the U.S. EPA SNAP Refrigeration and Air Conditioning guidance.
